To all whom it may concern.-

Be it known that I, GEORGE D. COREY, of Lowell, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Bottle-Stoppers, of

which the following is a specification.

My invention relates to bottlestoppers; and it consists in certain improvements upon the bottle -stopper patented to M. J. Hinden,

IO April 11, 1876, No. 175,981.

In the drawings, Figure l is a top view of the bottlestopper as applied to the neck of a bottle containing my improvements. Fig. 2 is a side elevation of the same, partly in section, showing the method of attaching the working parts of the Stopper together. Fig. 3 is a bottom View of the revolving cam-piece. Fig. 4 shows a vertical section of the revolving cam-piece. Fig. 5 is a bottom view of the sliding plate upon which the cam piece works. Fig. 6 is a side elevation of the same.

Ais the neck of the bottle, having the neckbandO and the bail B attached to it. E is the rubber stopper. F is the plate to which it is attached, sliding up and down on ears on the bail. D is the cam-plate resting on the plate F, and by the rotation of which the rubber stopper is compressed against the mouth of 3 the bottle. These parts are in general form and relation to the bail as heretofore constructed; but the mode of connecting the same together to form a cheap, durable, and convenient bottle-stopper is the subject of my present improvement.

From the lower side of the cam-plate D, I project a pin, d, axially downward, and on one side of it, at its lower end and projecting laterally from it, I form a shoulder, d. This 0 pin d is fitted to enter a corresponding hole, f in the plate F, and on one side of this hole I cut a notch, f corresponding with the projection d of the pin d, and adapted to receive the same when the pin d is inserted in proper 5 position into the hole in the plate F. The cylindrical part of the pin cl, between the lower face of the cam-plate D and the upper side of the projection d, ismade long enough to extend through the plate F, so that when the pin (Z and projection d have been inserted into the hole f and slot or notch f the projection dpasses entirely through the plate F, and can then be turned around freely by the revolution of the cam-plate D, the construction of this connection of the cam-plate D and plate F being somewhat similar to what is known as a bayonet-joint.

The slot f in plate F is in such a position with relation to the bail B when the plate F is slipped onto the bail that the thumb-piece of the cam-plate D, coming against the bail on either side,will prevent the projection d from coming opposite the slot f and allowing the cam-plate D to escape fromits connection with the plate F. At the same time, if desired,by

slipping the plate F off the bail, it may be detached instantly from the cam-plate D. By this construction the cam-plate D and its pin (1 may be cast in. one piece, finished ready for use, and amultiplicity of separate parts and expense in fitting the same together are avoided.

On the lower side of plate F, and around its axial hole y, I form a hollow tubular downward projection, f, terminated at its end by an outwardly-projecting annular flange, f, and I form the rubber stopper-piece E with a corresponding cavity in its upper side, so that it can be sprung over the flangef and tubular projection f, and be held united by its elasticity to the plate F, while at the same timeit cannot interfere with the pin d, which rotates within the tubular cavity of the projection f. I am enabled by this construction to cast the plate F and its tubular projection f and flange f in one piece,finished ready for use, and thus construct very cheaply and easily the connection between the rubber part E and it.

In order to avoid friction of the lower sur- I face of the cam-plate D upon the plate F, I form the cam-plate with an annular flange, d projecting slightly from its lower face and around its edge downward; so as to take a bearing upon the top surface of plate F, and in this manner the cam-plate is made to turn more easily than when its entire lower surface, or Substantially all ofit,bears upon the plate F. It is obvious that myinvention is not confined to the precise arrangement shown, although I consider that preferable. For instance, the

annular flange d may be made upon the top of the tubular projection f, adapted to receive the plateF, instead of the bottom surface of the lower end of the pin d and allow the same the cam-plate .D; or the pin (Z and its projectto rotate thereiu,with the elastic piece E, fitted 2o ing piece d may be formed upon the plate F around the outside thereof, substantially as 5 and project upward, working through the hole described.
